MICHIGAN — Of all 50 states, Michigan now has the cheapest gas prices in the entire country, according to data from GasBuddy.com. But it likely won’t last long.

Michigan’s average price for a gallon of gas is $1.802, barely beating out Oklahoma’s $1.804 per gallon.

Nationally, the average is around $2.03 per gallon.

GasBuddy.com analyst Patrick DeHaan said on Twitter it was back on Feb. 26, 2009—more than 2,400 days ago—that gas prices were this low in the state. DeHaan also said it’s likely the lowered prices won’t last more than 24-48 hours.

Why the drop?

DeHaan says it’s likely because of some ‘healthy competition’ as gas stations are continuing to try undercut each other. But he said it won’t stick around.

“I expect an upward adjustment likely tomorrow as most stations have been selling at a loss,” he told FOX 17. “I’d top off tonight, but wouldn’t get too excited when prices rise, because I’m expecting they’ll stay under $2 more often than over it thru the rest of 2015.”

Both Kalamazoo and Van Buren counties are averaging the cheapest gas prices with an average of $1.60 per gallon.

Missouri has the third cheapest gas in the state with an average price for gallon around $1.817.

Gasoline prices in Michigan tumbled to their lowest point in about 10 months, and analysts expect prices to keep falling.

The average price of an unleaded gallon of gasoline fell to $3.27, down 13 cents from a week ago, according to AAA.

In metro Detroit, it was a similar story. The average price dropped 10 cents to $3.31 per gallon.

“Decreased demand, relatively lower crude prices and the cost savings associated with producing winter-blend fuel will likely keep downward pressure on the price for retail gasoline,” AAA Michigan said in a statement. “Barring any major disruptions in supply, drivers are expected to see some of the lowest autumn prices since 2010.”
